A.2 Adding the measurement to a channel
The measurement from the CL17 Analyzer must be associated with a channel on the
AquaTrend Interface so the measurement will be shown on the AquaTrend display.
Attach the measurement to a channel as follows:
3. Select
AQUATREND MENU and press the ENTER key.
4. Select
DISPLAY SETUP and press ENTER.
5. Select
MEASUREMENT TO CHANNEL and press ENTER.
6. Select
ATTACH and press ENTER.
7. Select a available channel on the AquaTrend and press
ENTER.
8. Press
ENTER again to select ATTACH TO CL17.
9. Press the MENU key to return to the AquaTrend main display. The reading will be
displayed and updated every 2.5 seconds.
A.3 Alarms and warnings
If an alarm or warning condition exists at the CL17 Analyzer, the alarm or warning will be
indicated at the AquaTrend via the alarm annunciator. The actual alarm or warning must
be viewed and resolved at the CL17 Analyzer. The CL17 Analyzer alarms and recorder
outputs can also be connected to a Signal Output Module. Please refer to the Signal
Output Module Manual.
A.4 Logging data using the serial input/output module
The CL17 Analyzer sends the chlorine reading (in ppm) to a SIO on the network, if one is
present. The service diagnostic data must be disabled before outputting data to the SIO:
1. Press the
MENU key then the DOWN ARROW key until SETUP is displayed.
2. Press
ENTER.
3. Press
ENTER when DIAG OUTPUT is displayed.
4. Use the up or
DOWN ARROW key to toggle the selection between ON and OFF then
press
ENTER to select the displayed option. Press the EXIT key to return to the
measurement display.
The format of the data is illustrated below, where n is the SIO channel number for the
CL17. (The channel number (1–8) is assigned based on the order in which devices were
added to the network.) Please refer to the AquaTrend Interface Manual for information on
determining the channel number.
Note: In the following commands, n signifies the channel number.
[n]3.00,<CR><LF><NULL>
Additional diagnostic strings will be present if service diagnostics is enabled. These
diagnostics are for service personnel only.
